We study cylindrical and spherical shell structures that have cloaking material properties proposed by Pendry et al. We use 2D and 3D time-harmonic analysis to study the field distribution and power flow for various arrangements of these structures. We have shown that the COMSOL RF ... Read More
The Microwave Electrothermal Thruster (MET) is a space electric propulsion device that uses an electromagnetic resonant cavity within which a free-floating plasma is ignited and sustained, heating a propellant gas that is that exhausted out of a gas-dynamic nozzle. For an empty cavity ... Read More
A program for self-consistent modeling of electron-hole energy spectrum and space-charge distribution in III-nitride based quantum well (QW) structures has been developed. The model takes into consideration full 6-band description of the valence band states, nonparabolicity of the ... Read More
Thermal ablation of malignant tumors has been conducted in patients who are not candidates for surgery for more than ten years. Recently it has been shown that low energy DC pulses can cause cell necrosis. An undesirable characteristic of DC pulses in-vivo is the stimulation of skeletal ... Read More
The performance of simplified cylindrical cloaks with various material parameters was investigated. The performance metric was the overall scattering width of the cloak with various objects in the hidden region. COMSOL was used to simulate three cloaks with different material parameters ...

We calculated the spatial distribution of the electric fields induced in the brain during transcranial current stimulation (TCS). The spatial focality obtained using ‘concentric-ring’ configurations is investigated using a realistic MRI derived 3D finite element model of the human head. ... Read More
Accurate and efficient computation of electrical parameters for different conducting bodies represents an essential part of spacecraft modern integrated circuits. In this paper, we will illustrate modeling of inhomogeneous quasi-TEM shielded rectangular, cylindrical, and triangular ... Read More
Due to the complexity of electromagnetic modeling, researchers and scientists always look for development of accurate and fast methods to extract the parameters of electronic interconnects and package structures. In this paper, we illustrate modeling of multiconductor interconnects in ... Read More
One of the primary reasons for large power fluctuations in smelting furnaces is loss of contact between the electrode and ore. Therefore one of the important aspects of controlling power fluctuations is a predictive algorithm for the positioning of the electrode. We propose a model ... Read More
Signal processing algorithms for chemical sensing/monitoring have been subject of considerable research interest in the recent years mainly due to their diverse applicability. When the concentration of chemical agent is small, the dispersion of particles is governed by stochastic ... Read More
